Blue Mind Living: Why Water Makes You Happier and Healthier

What is "Blue Mind"?

"Blue Mind" is a term coined by marine biologist Dr Wallace J. Nichols to describe the calm, meditative state many of us feel when we are near, in or under water.
It's the feeling you get by the sea, beside a lake, or in your own hot tub at the end of the day.

Nichols argues that being around water has a real effect on how we feel, helping us relax and lifting our mood. Put simply: water makes us feel good.

Why water feels so calming

Nichols contrasts "red mind" (stress, overthinking, constant stimulation) with "blue mind" (calm focus and a more settled mood). Time in or near water helps people shift from one to the other. Many people notice:

• Less stress: the sound and movement of water help you switch off.
• A better mood: most of us simply feel happier near water.
• Better sleep: a warm soak relaxes the muscles and helps you wind down before bed.
• Clearer thinking: many people say their best ideas come while they're soaking.

How your spa brings Blue Mind home

You don't need a sea view to get the benefit. A hot tub offers a similar experience every day:

1. Something calm to look at: moving water and soft reflections are easy on tired eyes and minds.
2. Soothing sound: the bubbling of the jets is like natural running water.
3. Physical comfort: the water supports your weight, taking pressure off joints and muscles.
4. Warmth: warm water helps your whole body relax.

Fifteen to twenty minutes in the spa is often enough to reset your mood and leave you feeling refreshed.

A simple Blue Mind routine

Try this to make your hot tub time more restful:

1. Soak at sunset: the changing light and colour are a lovely backdrop.
2. Leave your phone inside: no screens, just the water and your thoughts.
3. Breathe slowly: match your breathing to the rhythm of the jets.
4. Add scent or sound: soft lighting, gentle music or nature sounds all help.
5. Take a moment to reflect: let the day's tension go.

Calmer, one soak at a time

Blue Mind living isn't about escaping everyday life. It's about making regular time for calm and quiet.

Your hot tub is an easy way to build that into your day.

What the evidence says

"Blue mind" is the idea that time in or near water can leave people feeling calmer. Research into "blue spaces" such as coasts, rivers and lakes has found that many people report feeling better after spending time there, but most of it is observational, so it shows links rather than proof. A hot tub is not a cure for anything. It may help you relax and make time for yourself, which fits well with everyday NHS advice on wellbeing.

The NHS five steps to mental wellbeing are a useful framework: connect with other people, be physically active, learn new skills, give to others and pay attention to the present moment. Its Every Mind Matters wellbeing tips add practical ideas. If you are feeling low for more than a couple of weeks, talk to your GP.

Practical ways to bring water into your week

Beyond the hot tub

• A walk by a river, canal or the sea counts as blue space, and walking is great physical activity. The NHS sets out physical activity guidelines for adults.
• Cold water is popular too. Read our comparison of chill tubs and hot spas before trying it, and see our chill therapy spas.
• Even the sound of water, from a small garden water feature, can make a space feel calmer.

Keep it safe

• Keep soaks to 15 to 20 minutes at 37°C to 38°C for adults.
• Drink water before and after.
• You shouldn't use a hot tub or sauna while pregnant.
• If you have a heart or blood pressure condition, check with your GP before using a hot tub.
